T @ZZ whom it may concern: j

Beit known that I, EDDY T. MOKAIG, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois,

have invented a new and useful Improvement in Car-Seats, of which the following is a specification.

This invention relates to the supports of the reversible backs of car-seats'of the type xo in which the back moves from one side of the seat to the other without turning over.

The object of the invention is to provide a simple, strong, durable, and economical construction of the supports which can be easily t5 operated and in the manufacture of which commercial sizes and shapes of flat metal can be largely used.

The nature of the invention will be fully understood from the accompanying drawings,

zo in which-- Figure lis an elevation of my improved devices for supporting the reversible back of the carseat. Fig. 2 shows the same devices in the reversed position from that given in Fig. 1. Fig. 3 is a plan ofv the Vparts in the position of Fig. 2,' and Fig. t is a detail view.

In said drawings, 4 represents the end of the seat-frame, and 5 is an upstanding arm to which the end of the back may be secured 3o 4and by which it is supported and positioned at the angle desired for the back, the back itself not being shown. The supports other than said arm 5 consist of two main elbowshaped links 6 and 7, short connecting-links 3 5 8 and 9, and the pivots uniting said parts to each other and to the seat-frame. Of these the pivot 10 is xed and passes through the angle of link 6 and the lower end of link 9. The arm 5 has two connections to the fixed 4o pivot, one by means of the long arm of link allel and retain their parallelism, one of them only shifting somewhat longitudinally during changes in the position of the seat-back, and the long arms of the elbow-links also remain substantially parallel, though in moving from one position to the other link 6 moves 55 in front of and from one side tothe other of link 7. f

The movements of the parts are limited by means of a pin 16, carried by link 9, and the slot 17, formed in a stationary plate 18, at- 6o tached to the seat and traversed by the pin. This regulates the positions of the seat-back, as will be understood.

While have shown the mechanism as applied to only one end of the seat and back, it will be understood that duplicate mechanism vwill be applied to the other end thereof.

In the operation of the seat the link 8 is of great benefit, as it renders the reversing movement steady and even and controls the 7o main links and prevents any independent movement by either of them, so that they cannot lose their proper relative positions. The link 7 has also a lateral extension 19,

making it a complete T in form. The edge of the head of this T comes in contact with the top edge of plate 18, and in order that it may not bind on said plate the edge of the T is curved, as shown at 20; This head dur-l ing a portion of the reversing operation bears 8.o at each end on said plate 18, as seen at Fig. t, and steadies the movement by preventing any wabbling of the mechanism during that time. g

I claim1 85 1. The combination with a back-supporting arm, of two main links supporting saidarm and joined to it at separated points one above the other, a pivot supported in a stationary part of the seat-frame and upon which 9o one of said links is pivoted, a connection between the other main link and said pivot, a stop on said connection and a slot ony said stationary part engaged by the stop and enabling it to limit the swing of said arm, sub- 9 5 stantially as specified.

2. The combination with a back-support ing arm, of two main links supporting said arm and joined to it at separated points one above the other and also having lateral exroo tensions, a pivot supported in a stationary part of the seat-frame and upon which one of said links is pivoted, a connection between the other main link and said pivot, and a second short link connecting together said lateral extensions upon the main links, substantially as specified. f

3. The combination with the seat-frame of a back-supporting arm, two elbow-shaped main links pivoted to said arm one above the other, a pivot secured to the seat-frame and directly supporting the lower main link, and two short links, one connecting the upper main link to the pivot and the other connecting together the elbow portions of the main links, substantially asfspecifed.

4. The mechanism for supporting the re! versible back of a car-seat, having in combination an arm to which the back may be attached, a movable link 7 pivoted at one end to said arm, and supported at its other end by a pivoted link 9, said link 9 and a stationary plate 18 over which said link 7 rides during the reversing operation, substantially as specified.

5. In mechanism for supporting the reversible back of a car-seat, the combination of a back-supporting arm, a link 7 pivotally attached to said arm, and moving with it in the reversing movement-s and forming one of the supports of the arm, and also having a wide base, and a stationary horizontal surface over which the base of the link moves, substantially as specified.

6. In mechanism for supporting the reversible back of a car-seat, the combination of a back-supporting arm, a link 7 pivotally attached to said arm, and moving with itin the reversing movements and forming one of the supports of the arm, and also having a wide base, and a stationary plate 18 over which the base of the link rides during the inter mediate portion of the reversing movement, substantially as specified.

7. In mechanism for supporting the reversible back of a car-seat, the combination with an arm for supporting the back and the mechanism supporting said arm, such mechanism including a link 7 with a Wide base, of a stationary controlling-surface over which such base of link 7 rides during the intermediate portion of the reversing movement, substantially as specified.

8. The mechanism for supporting the rcn versible back of a oar-seat, having in combination an arm to which the back may be attached, a movable link 7 made T-shaped at one end and pivoted to said arm at its other end, and also supported bya pivoted link 9, said link 9 and a stationary plate 18 over which said link 7 rides during the reversing operation, substantially as specified.
